Umami is a lot more present that people recognize. I've built up an intuition for this over the years, and also sort of trained my tongue.
What we call umami is a subjective experience that has an underlying molecular cause, but it's complicated: more than one molecule contributes to the sensation, different foods have different molecules, many people can't recognize it on its own, etc.
The most easily recognized umami tastes seem to come from hydrolyzed soy protein and yeast extracts- both are added to tons of food. The canonical example is Doritos, which are a masterpiece of modern food industrial optimization. Doritos are mostly corn, but they also add whey (cheese derived umami), MSG (molecular, isolated glutamate in salt form), buttermilk (multiple flavors including umami), romano cheese (more umami!), tomato powder (umami), inositate (umami). It's basically an umami bomb.
From what I can tell, the best umami flavors come from a combination of several different molecules combined with some salt. the combination seems to potentiate the flavor significantly. You can also saturate out your receptors- if you drink a highly concentrated broth, you'll see there's some upper limit to the amount of umami you can taste and after that, additional aminos are just wasted.
